Answer: Pulsars</h2>
A <u>pulsar</u> is a neutron star that emits very intense electromagnetic radiation at short and periodic intervals ( rotating really fast) due to its intense magnetic field that induces this emission.
Nevertheless, it is important to note that all pulsars are neutron stars, but not all neutron stars are pulsars.
Let's clarify:
A neutron star, is the name given to the remains of a supernova. In itself it is the result of the gravitational collapse of a massive supergiant star after exhausting the fuel in its core.
Neutron stars have a small size for their very high density and they rotate at a huge speed.
However, the way to know that a pulsar is a neutron star is because of its high rotating speed.
Conduction: someone burning their hand by placing their hand on a hot stove.
Convection: Food cooking in an oven.
Radiation: The heat we feel from the sun.
<span>An object is located 51 millimeters from a diverging lens the object has a height og 13 millimeters and the image height is 3.5 millimeters how far in front of the lens is image located?</span>
Answer: Given mass of man = 85kg
Distance crate was pushed = 4m
Force exerted on crate = 500N
Angle inclined = 20°
Let Total force exerted Ft = (mg * sin(20)) + 500
Ft =( 85*9.81* sin20°) + 500
Ft = 758N
Work done Wd = Ft * distance
Wd = 785 * 4 = 3.14 * 10^3J
Waves in which the displacement of the medium is in the same directions as, or the opposite direction to, the traveling wave's direction.
A wave in which the particle movement is parallel to the wave's direction.
I gave to definition, I hope you understand it. Have a nice day :)
